VITREOSIL FUSED QUARTZ
CRUCIBLES «RETORTS· MUFFLES DISHES «TANKS · POTS «TRAYS Crucibles made of VITREOSIL guard the real purity of your compounds. They are non-absorbent, non-catalytic, non-porous; can be wire-wound for elec trical heating; are immune to extreme electrical, chemical and thermal con ditions. Available in transparent, glazed or unglazed styles. VITREOSIL Dishes are ideal for concentrations, evapora tions, crystallizing acid solutions. All sizes and types. Trays and other VITREOSIL ware in many sizes from stock, or prompt delivery of special sizes.
ELECTRIC IMMERSION HEATERS BALL & SOCKET JOINTS STANDARD TAPER JOINTS GRADED SEALS Corrosion-resistant VITREOSIL equip ment is impervious to all organic and inorganic chemicals even at very high temperatures, regardless of concentra tions, except strong caustics and hy drofluoric acid. Outstanding electrical and high t e m p e r a t u r e properties, strength, impermeability. In stock sizes for immediate shipment. Custom items to order.
